DEMOUNThBLE Application filed February 1'5, 1927. Serial No. 168,779.

The invention relates to a wheel rim, more especiallyto the class o't. demountable rims for automobile wheels or the like.

'llheprim object of the invention is the provision of a rim of this character, in a manner as hereinafter set forth, wherein the casing or shoe of a pneumatic tire can be conveniently and easily mounted upon the run, without exer'en or excessive labor on the part ot person, either when required "to demount the casing or shoe from the rim or mount the same thereon.

Another object oi the invention is the provision of a flanged rim, in a manner as hereinafter set forth, wherein a segment of the flange of said rim at one side thereof can be shifted to a position to permit a tire to be readily and conveniently placed upon the rim or removed theii'eljrom, and further wherein the rim is provided with means acting, when the tire is upon the rim, to tiri'uly and securely clamp it without liability of its creeping thereon circum'l erentially of the rim or of lateral displacement to either side ofthe same.

A still further object of the invention is the provision of a. rim of: this character, wherein the construction thereof permits its use as a tire carrier when demounted from wheel and materially simplifies the application and removal of a tire on and from the same.

A still further object of the invention is the provision of a rim of this character, which is comparatively simple in construction, thoroughly reliable and etlicient in its purpose, strong, durable, andinexpensive to manufacture.

\Vith these and other objects in view, the invent-ion consists in the features of corn struction, combination and arrangement of parts, as will he hereinafter more fully described. in detail, illust ated iuthe ac coiupanying drawings. showing the pre terred embodiments of the invention, and pointed out in the claims hereunto appended.

In the ai'rcompauying drawings:

Figure 1 is a side elevation ot a vehicle wheel showing the demountable rim con structed in accordance with the intention applied and supporting a tire.

Figure 2 is a top plan view of the rim showing the tire removed with the displaceable clincher flange in position for clamping the tire upon the rim.

Figure 3 is a view similar to Figure 2 showing the displaceable clincher Hanger swung to position for the mounting or a tire or the demounting thereof on and from the v p to Figure 4 is a sectional view on the line 4 l of Figure 1 looking in the direction rim Similar reference characters indicate corresponding parts tl roughout the several views in the drawings.

Referring to the drawings in detail A designates generally a vehiclewheel oi the automobile type, B the telloe thereof, Othe demountable rim carriednpon the felloe and D the pneumatic tire upon said rim. The wheel A and its telloe B are of conventional form, the latter being of the stamped metal type and having at the inner side of the wheel, the usual circuml ercntially disposed outwardly curved abutment lip 10, for the demountable rim C, When engaged upon the felloe B, as will be clearly apparent in Figures 1 to 7 inclusive of the drawings.

The rim C comprises a comparatively relatively wide unbroken annular body or band 11, having at its inner edge an outwardly and inwardly curved inside clincher flange 12, disposed circum'iercntially ot said rim and continuous throughout the. body or band 11. This flange 12 isdesigned to abut the circumterential lip on the tellce, when. the domountahle rim U is engaged upon the wheel, as is usual or customary.

Formed throughout one half ot'. the circum'iference ot the demountable rim 0 and integral with the body or hand 11. thereo; at the outside and opposite the flange 3.52 is a companion clincher flange 13, which in its confronting relation to the inside clincher flange 12, will cooperate to "fasten the casing or shoe ot the pneumatic tire D uponv the rim C in the usual well known manner.

Extending throughout the other halt 0t- P. ml

the circumference of the rim G at the outside thereof is a shit'tablo clincher flanged section 14:, connected at its ends with the flanged section 11-3, through the medium elf suitable hinges 15 so'that the section 'l-t can be swung upwardly and inwardly onto the band 11 or outwardly and downwardly to the position as shown in Figure 3 of the drawings. lVhen the section 14 has been opened or swung to the position as shown in Figure 3 ofthe drawings,.the tire D can be readily and eas ly mounted upon the run C Without exertion and with dispatch.

The body or band 11 is formed with an inwardlycurved lip or ledgelti to oppose the flange section 13 and further said lip or ledge is adapted to ride the inner periphery of the casing or shoe of the tire I) to guide the same when being mounted upon the rim C, and to facilitate such mounting u on said rim, the lip or ledge 16 being cl darly illustrated in Figures 3, 6 and 8 0t the drawings.

Integral with the flanged section 13 are spaced lugs 17. Integral with the flanged section 14 are spaced lugs 18. The lip or ledge 16 is provided with spaced notches 19 to receive the lugs 18. The lip or ledge 16 is provided with spaced lugs 20' and which are connected tothe lugs lS by holdtast devices 21. Bolt members 22 are provided for securing the lugs 17 against the body or band B. With reference to Figure 5 the lugs 18 and20 are shown connected together by the holdfast devices 21' and with reference to Figure 4; the lugs 17 are shown secured to the body B by the holdt'ast devices or bolt members 22. y I

The rim C is clemountably engaged on the felloe B of the wheel A in the customary or usual manner and on the demountmg oi? the rnn Gthe latter can be ut lized as a tire carrier employed in the customary manner.

Then it is desired to mount the the D upon the run C, t is only necessary to re move the boltsor :tastenlngs 21 from engagement with the lugs 18'and20, therebyfree mg the section 14 and on the swinging ot the same upwardly and downwardly as is shown in Figure 3 of the drawings, the tire D can be readily slipped upon the rim G for the mounting of said tire thereon. 'lhcreafter the section 14 is closed relative to the rim G and the bolts 21 engaged in a manner as hereinbet'ore described, so that the tire I) will be clamped upon the rim. The do mounting of the rim G from the .telloc 13 of the wl'lcel A will be obvious.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood and there fore a more extended explanation has been omitted.

What is claimed is 1. A rim comprising an annular rim hotly having its inner side provided with an endless concentric flange and its outer side provlded wltha flange and a hp, said ilnngc on the outer side of the riinbody extcndizu, a

portion out the cn'cumterence thereof, said lip extending the remaining portion of the circumference of said body, an outwardly and an inwardly movable flange section coextensive with said lip and adapted to sea 1 on the latter when swung inwardly thereby forminga continuation of said outer flange, means for hing-mg said section to said outer flange, means for detachably crmnecting the rim body to a felloc said tip imrmed with spaced notches and inwardly extending; lugs,

each lug arranged at the base 01'' a notch, int vided with a flange and a lip, said flange on the outer side of said rim body extending a portion of the circumference thereof, said l p extend ng the remannngportion ot' the circumference of said run body and outwardly and inwardly movabletlange section (re-extensive with saidlip and ada ited to seat on the latter when swung inwardly to form a continuation ott said outer flange, means tor longing said scction to said outer flange, means :ton'detachably connecting the rim body to a itclloe, said lip formed with spaced notches and inwardly extending lugs, y

each leg positioned at the base of a notcln inwardly extending spaced lugs on said sec tion for positioning in said notches to oppose the lune on the lip when said section is seated on the lip, said lugs on said 111; being aperturcd and having the walls of the open tures thereof threaded, said logs; on said section being apertnred, and means extending through the apertures of said opposed lugs and tln'endedly engaging with the lngi-i;

on the lip for maintaining said section ll] seated position.

In testimony whereot', we allii; our signzn tures hereto.
